Abstract
In this paper
the high temperature properties of 1.3 μm laser diode are discussed. The reverse mesa RWG structure is introduced into 1.3 μm AlGaInAs/InP MQW LD and applied to fabricate the uncooled laser diode with high performance and improved temperature characteristics. The threshold current as low as 6 mA
and characteristics temperature as high as 95 K between 25 ℃ and 85 ℃ are obtained
which are the best results in the literatures until now.
